Specification of Letters Patent.

Patented Dec. 18, 1906.

Application filed February 12, 1906. Serial No. 300,648.

To all whom it may concern.-

Be it known that I, CHARLES H. SHEPLER, a citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Smoke-Consumers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in devices for consuming the smoke and combustible gases and accelerating the combustion in the fire-chambers of stoves, furnaces, and like structures, and has for one of its objects to simplify and improve the construction and increase the efficiency and economy in fuel consumption of devices of this character.

Another object of the invention is to provide a simply-constructed device of this character in which ashes, dust, and other material resulting from the'combustion are effectually prevented from finding lodgment with in the improved device and from which material of the character specified is readily removable.

These and other objects are attained b means of the construction illustrated in the accompanying drawings, in which Figure 1 is a vertical section of a fire-pot made in accordance with my invention. Fig. 2 is a plan view of the same. Fig. 3 is a detail perspective view showing a modification adapted to be applied to a rectangular fire-pot or furnace.

Referring to the accompanying drawings for a more particular description of my invention, the numeral 1 designates the side walls of a fire-pot of the usual or any preferred construction provided with openings 2 in the side walls thereof, said openings being preferably of inverted-V shape and being located at the required distance above the grate 3 to admit air at a suitable point above the burning fuel in order to promote the combustion thereof and to consume'the smoke and other gases arising therefrom. The openings 2 are covered by a surrounding tube 4, formed integral with or secured to the side walls of the fire-pot at a point above or in line with the openings 2, with the bottom of the apertures flush with the bottom or the floor of the tube, so that depressions or cavities are not produced for the lodgment of ashes and the like, as hereinafter explained. At

the front ends of the tube 4 are dampers or draft-regulators 5, of any suitable construction, said regulators being preferably secured to a cap 6, fitted upon the outer ends of the tube 4. The walls of the tube 4 merge into the damper-supporting portions or terminals of the same, so that no obstructions occur to retard the free passage of the air into the tube or the removal of ashes, dust, and like material therefrom.

In the modification shown in Fig. 3 the tubular portion 4 is rectangular in plan and is adapted to be secured to a fire-pot in any suitable manner and opens thereinto by means of openings similar to those shown in Fig. 1. For the purpose of cleaning the tube shown in this figure a cap or cover 4 is secured at one of the corners.

The operation of my invention may bev described as follows: When it is required to promote the combustion of the fuel in the fire-pot, the dampers 5 are opened to admit air into the tube 4, the air in which enters through the openings 2 into the fire-pot and promoting the combustion of the gases therein. The dampers may be regulated to supply the amount of air required for different conditions existing inthe firepot.

The floor of the tube 4 and 4 being flush with the bottoms of the apertures 2 and the latter being horizontal, any ashes, cinders, or like material which may pass into the tube can be readily removed either through the apertures or through the spaced terminals or tube after removing the caps 6 therefrom. The interior of the device being free from depressions or obstructions precludes all possibility of the lodgment or accumulation of dust or ashes therein. This is a very important advantage and materially increases the value and efliciency of the device.

The tube 4 is preferably integral with the fire-pot. The apertures 2 being of greatest width at their lower ends, with the side walls uniformly converging toward the top, effectually prevents the lodgment of ashes or dust or like material therein, and thereby obstructing the apertures. The novel form of apertures thus shown are self-cleaning, which is also an important advantage in devices of this character.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

IIO

spaced apertures through its side walls, and a 1 tube extending around the chamber and inclosing said apertures with its terminals spaced apart and provided with detachable caps having intake-apertures, the interior of the tube gradually merging into said terminals and preventing the formation of recesses therein.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

CHARLES H. SHEPLER.
